lATTEltN-CHAIN RACK.

Specilcati'on of Letters Patent.

Application filed August 24, 191..,

Be it known that l, Loris ll. liwnnr, a citizen ot the llnitetl fitates,:nul resident et Uxbridge, in 'the rountv ot' iv'oreester anti @State ofMassachusetts, have invented eertain neu' antl useful ln'iprovenuius inlatin llarrks, ot which the 'followingl is a speeilieation.

This invention relates to means tor sup limiting` the pattern chains otloonis lor weaving' fancy worsted or 'fancy rassiinere goods, and refersespeciallyv to the means 't'or supporting the pattern usetl tor the rainbos: motion. als my present invention is applicable to looms oi variouskiiuls, l do not attempt to illustrate or describe herein any details ofthe looin proper.

'The olojeet ot the invention is to provide a rack which will enable achain ol' great length to be employed within a roinpaet space, the rackproviding iter the auton'iatie assenibling of the portions ot' the chainwhich are not operating with the -if'ibrating ine/.zhanisnn in the lormof a series oli' loops or testoons.

. '.lo these encls the invention oonsists in the chainsupporting racksulostantiall7 as hereinafter ilescriberl and elainierl.

Qi. the accompanying orawings: Figure l is a ilan vieur el my inipiw"eel chain rack; Fig. 2 is a side elevation of the saine, said ligurealso illustrating one of the vibrator levers oit a loom; Fig. 3represents a section on line 3`3 of Fig'. Q.

Similar reference Characters indicate 'the saine or similar parts in allof the views.

To an upright l0, which may be a portion oi" the frame of a leoni, issecured the rack, comprising two brackets ll havingV traek portions l).Two guide arms 13, which may be oonneetetl together in the yoke, areconnected to the bracket ll by i bolt 14 so that the arms 13 can beadjusted as to their angle relatively to the tracks l2. isingfrom. theouter ends ot' the brackets ll are uprigrlis l5 having their upper endsslotteil to permit of the atljusahle eonneetion therewith of the guide.ivliioh.

Ms snou'n in Fig. l, the two traf-,ks lf2 are so spar-tlthat onl -the long` bars having wheels ran-reach foin one trank to theother, the upper tracks orA lguides 1G being closer together so that allof the bars will ride thereupon. f ln operation the Cylinder QS) ehainstep by step in the direction of the ala-ou', lfigx i), all oit the barsritlii' j up the upper guides 1G and over theevliinlerQ9,the cani rollsE25 thereof, acting' upon the vibrator levers 2h', selecting whichlevers 26 shall be actuated by the relative spacing of the earn rolls 25upon lherorls, in the usual manner. l`hehokler1 to ratain the chainproperljy1 upon the upper guides US regardless ot the amount of jarriie," to which the rack is subjected by 'the action of the loom 'when therack is supported by the traine of the loom.

Said upperguides 16 render it certain that the chain will pass over the cylinderQllwith the cam rolls of the rods in proper positions to select thevibrator levers that are to he actuated, the holders 22 preventing thechain from being jarred away from proper position. rlie upper guides 16have their upper ende of Course. extending into close proximity to theflanges of' the cylinder 29 so that the chain 1will pas#` readily amlaccuratelyY onto the latter.
